Found: Looking for a unique fic

[periphescent.livejournal.com]

Hello guys! So I'm new to the community and have been seeking to expand my list of favorite recs. Like a newbie, however, I read a fic not too long ago and am now trying to find it once more. I'm pretty certain I found it on a tumblr user's fic rec page, but I've checked all the ST/spirk blogs I follow and couldn't find it. I can't remember if I read it on my desktop, tablet, or phone, and I've gone back through several weeks of history to no avail. I tried combinations of search terms on ksarchive and ao3, but because of the specific situation involved, it is hard to pinpoint with pairing tags. I didn't save it because it didn't really strike a chord with me at the time, but of course now I've been itching to reread it.

It's set at the end of ST:XI when Spock is considering moving to the Vulcan colony. Rather than some mystic advice, Spock Prime gives him a pretty compelling reason not to: namely, a rather explicit video of his own Kirk (Kirk Prime). The sight of the video and the knowledge of Kirk Prime/Spock Prime's relationship in the original universe makes Spock reconsider his decision. Basically, it's a Kirk Prime masturbation/exhibition fic. There's no actual Kirk/Spock, and technically no Kirk Prime/Spock Prime, so it's really hard to find through tags. If anyone could help me find it, I'd love you forever!
